PivotGridControl.CollapseValueAsync(Boolean, Object[]) Method

Collapses the specified column or row asynchronously.

Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v19.2.dll

Declaration

C#

public void CollapseValueAsync(
    bool isColumn,
    object[] values
)

VB.NET

Public Sub CollapseValueAsync(
    isColumn As Boolean,
    values As Object()
)

Parameters

Name	Type	Description
isColumn	Boolean	true to collapse a column; false to collapse a row.
values	Object[]	An array of field values that identify the column/row to be collapsed.

Remarks

The CollapseValueAsync method is asynchronous. It starts executing the related operation in a background thread, and immediately returns control. The primary UI thread is not blocked, allowing the application to continue responding to end-user actions. For more information about the asynchronous mode, see Asynchronous Mode.

If you need to perform specific actions after this operation is completed, use another overload of the CollapseValueAsync method that takes the asyncCompleted parameter, and pass a delegate that performs the required actions as this parameter.

Consider the following PivotGrid control:

To collapse the “Austria” column (within the “Alice Mutton” column), use the following code:

C#

pivotGridControl1.CollapseValueAsync(true, new object[] {"Alice Mutton", "Austria"});

VB.NET

pivotGridControl1.CollapseValueAsync(True, New Object() {"Alice Mutton", "Austria"})

The result of this operation is shown below:

To collapse a column or row synchronously, use the PivotGridControl.CollapseValue method.

To expand a column or row, use the PivotGridControl.ExpandValueAsync (asynchronous) or PivotGridControl.ExpandValue (synchronous) method.
